Abstract
The interaction of sodium pyrene-3-sulphonate (NaPyS) with different l ipid monolayers at the air-solution interface was studied by monolayer techniques (surface pressure and surface potential measurements) and by spectroscopic techniques (fluorescence and reflection measurements) . The uptake of negatively charged NaPyS by non-charged and negatively charged phospholipid monolayers was induced by the presence of positi vely charged protein protamine in bulk solution.
